TL;DR: In this paper, an explanation of the anisotropic fracture behavior of heavily drawn steels is proposed on the basis of micromechanical considerations: the change in crack propagation direction can be explained by the oriented pearlitic microstructure of the steels.

Abstract: An explanation of the anisotropic fracture behaviour of heavily drawn steels is proposed on the basis of micromechanical considerations: the change in crack propagation direction can be explained by the oriented pearlitic microstructure of the steels. Apart from the standard pearlitic colonies (more or less oriented), an exceptional pearlitic pseudocolony can be observed, extremely slender and aligned in the drawing direction, which makes it a preferential fracture path with minimum local resistance.

Failure analysis of cold drawn eutectoid steel wires for prestressed concrete
Jesús Toribio,Andrés Valiente +1 more
TL;DR: In this article, a failure analysis of cold drawn eutectoid steel wires for prestressed concrete is presented, and an approximate procedure is proposed to estimate the fracture toughness of heavily drawn steels in both longitudinal and transverse (perpendicular) directions, on the basis of the critical load at the pop-in situation and at the critical failure instant (maximum load).

Delamination fracture of prestressing steel: An engineering approach
TL;DR: In this article, a composites engineering approach was used to explain the stress corrosion behavior of high-strength prestressing steel wires. But the results were limited to two eutectoid steels in the form of hot-rolled bar and cold-drawn wire.

HELP versus HEDE in progressively cold-drawn pearlitic steels: Between Donatello and Michelangelo
TL;DR: In this paper, the authors reviewed previous research in the field of hydrogen effects on progressively cold-drawn pearlitic steels in terms of hydrogen degradation (HD), hydrogen embrittlement (HE) or, at the micro-level, hydrogen-assisted micro-damage (HAMD), thus affecting their microstructural integrity and compromising the structural integrity of civil engineering structures such as prestressed concrete bridges.

Structural integrity of progressively cold-drawn pearlitic steels: From Raffaello Sanzio to Vincent van Gogh
TL;DR: In this paper, the microstructure of cold-drawn pearlitic steel wires becomes progressively oriented as the cold-drawing degree increases and this microstructural fact influences their macroscopic behavior by inducing anisotropic fracture and crack path deflection.
